Mismatched Capacity analysis in Grafana and Active IQ dashbaord

[RakutenStorage]

Hi All,
We have noticed inconsistencies in the capacity reporting data between Active IQ and the Grafana dashboard.

From the attached snippet, we observe the following:

1. According to Grafana, the volume used capacity is 1.65 TB.

2. According to Active IQ, the volume used capacity is 1.50 TB.

We have already confirmed that this discrepancy is not related to polling issues. However, this inaccurate capacity usage data has negatively impacted the accuracy of our capacity analysis reports.

Below are the details of our environment for your reference:

ONTAP Version : 9.13.1P13

Active IQ Version :9.14

Promethues Version : 2.30.3
Grafana Version: Grafana v7.5.17 (8441179413)
Harvest Version: harvest version 21.11.0-1 (commit 66c5ce1)

Hi - the discrepancy comes from the units.  Grafana is using TB (Terabyte) while ActiveIQ is using TiB (Tebibyte), so ActiveIQ will always show a lower number.  One TB = 1,000,000,000,000 bytes, one TiB = 1,099,511,627,776 bytes.

I believe that ActiveIQ is reporting TiB, not TB, so the capacity shown would be lower.
